SafetyDetectives spoke with Alex, the founder of Rinzler Labs and, about the cybersecurity risk and challenges associated with SIM card technology, how to mitigate scams, how SIM data is used, and more.

Hi Alex, thank you for taking the time to speak with me today. Can you talk about your background and what motivated you to start Rinzler Labs?

Certainly! My journey with Rinzler Labs began in 2017 when I had a strong desire to venture into the privacy sector. At that time, I came up with an idea to establish my private SMS platform exclusively for handling incoming messages, particularly focused on transactional purposes like verification SMS. As time went on, this concept grew and evolved, and today, thanks to the collaborative efforts of a small but dedicated team, we operate Rinzler Labs as a successful SaaS (Software as a Service) platform. Its scope has expanded well beyond my original vision, which is truly exciting.

Let’s focus on Crypton. Can you tell me about the main features and advantages of the Secure SIM card?

Crypton doesn’t offer a traditional physical SIM card service; instead, we provide a unique approach. Our service involves hosting physical SIM cards in our secure datacenter. Customers have the opportunity to rent these SIM cards for their exclusive use. We source SIM cards from different providers and countries, and through our SaaS platform, customers can securely purchase and utilise these physical SIMs.
The main features and advantages of SIMs hosted by Crypton include:

  • Robust Security: By storing physical SIM cards in our secure datacenter, Crypton ensures the highest level of data protection and privacy, making unauthorised access challenging.
  • Flexibility: Customers can access and use SIM cards from various providers and countries, offering flexibility for both local and international communication needs.
  • Easy Management: Our user-friendly SaaS platform simplifies the process of renting and managing physical SIM cards, making it accessible to a wide range of customers, using regular forms of payment such as credit cards, transfers and even cryptocurrency such as Bitcoin and Monero.
  • Global Reach: While primarily operating with UK SIM cards, Crypton has expanded its services to cover other regions like Europe and the Americas.
  • Cost-Effective Solution: By offering rental options for physical SIM cards, Crypton’s service provides a cost-effective solution for temporary or location-specific communication needs.

In summary, SIMs hosted by Crypton provide a secure, flexible, and convenient option for users to access physical SIM cards, ensuring reliable communication while prioritising data privacy and global accessibility.

What are the key cybersecurity challenges and risks associated with SIM card technology?

Sure, SIM card technology introduces several cybersecurity challenges and risks that necessitate careful attention. Cloning of SIM cards poses a significant threat, allowing attackers to create duplicates and impersonate legitimate users, leading to unauthorised access to phone numbers, calls, and messages. Hijacking is another concern, where cybercriminals exploit carrier system weaknesses or social engineering to transfer a victim’s phone number to a controlled SIM card, granting access to accounts relying on SMS-based two-factor authentication (2FA). Physical theft or loss of SIM cards allows attackers to extract sensitive information and potentially impersonate owners. Rogue base stations and IMSI catchers enable interception of communications, jeopardising SIM card data and privacy.

How does your SIM card solution address the potential vulnerabilities and risks introduced by emerging threats such as SIM swapping, remote SIM provisioning attacks, or other advanced attack vectors?

Our SIM card solution incorporates a multi-layered approach to address the potential vulnerabilities and risks associated with emerging threats, including SIM swapping, remote SIM provisioning attacks, and other advanced attack vectors. Firstly, we implement robust authentication mechanisms on the SIM card itself to prevent unauthorized cloning or tampering. To counter SIM swapping attacks, our solution employs enhanced identity verification protocols during SIM activation/registration. We work closely with mobile network operators to establish stringent procedures that require multiple authentication factors, reducing the likelihood of successful SIM swaps through social engineering or other means. To tackle other advanced attack vectors, such as rogue base stations and IMSI catchers, our modems are equipped with sophisticated anomaly detection capabilities. These features enable the modem to detect potential malicious base stations and take appropriate actions to safeguard communications. In addition to the technical measures, we also focus on user awareness and education. We promote best practices to our users. Overall, our SIM card solution is built on a foundation of security, with a proactive and adaptive approach to mitigating emerging threats.

What does the average person not know about how their data is used with a regular SIM card?

The average person may not be fully aware of how their data is used with a regular SIM card. This includes location tracking, metadata collection from calls and messages, data sharing during roaming, and usage in marketing and advertising. SIM cards also play a crucial role in two-factor authentication processes, but they can be vulnerable to SIM swapping attacks. Additionally, mobile network operators may cooperate with law enforcement for surveillance purposes when required. Understanding these aspects can help individuals make more informed decisions about their data privacy and digital activities.
